Detailed Description

Interface for all biological file format readers and writers.

Note

The Java implementation includes a getNativeDataType method; this is not included in this implementation.

Member Function Documentation

static void ome::files::FormatHandler::assertId ( const boost::optional< boost::filesystem::path > &  id, bool  notNull = true  )

inlinestatic

Assert that the current file is valid.

Assert if the current file is null, or not, according to the given flag. If the assertion fails, an exception is thrown.

Parameters

id	Filename to test.
notNull	true if id should be non-null, false if id should be null.

Exceptions

std::logic_error

if the assertion fails.

Here is the caller graph for this function:

static bool ome::files::FormatHandler::checkSuffix ( const boost::filesystem::path &  name, const boost::filesystem::path &  suffix  )

inlinestatic

Perform suffix matching for the given filename.

Parameters

name	the name to check.
suffix	the suffix to match.

Returns

true if the suffix is suppored, false otherwise.

Referenced by checkSuffix(), ome::files::in::OMETIFFReader::initFile(), ome::files::in::OMETIFFReader::isSingleFile(), ome::files::in::OMETIFFReader::isThisType(), ome::files::detail::FormatWriter::isThisType(), and ome::files::detail::FormatReader::isThisType().

Here is the caller graph for this function:

static bool ome::files::FormatHandler::checkSuffix ( const boost::filesystem::path &  name, const std::vector< boost::filesystem::path > &  suffixes  )

inlinestatic

Perform suffix matching for the given filename.

Parameters

name	the name to check.
suffixes	the suffixes to match.

Returns

true if the suffix is suppored, false otherwise.

static bool ome::files::FormatHandler::checkSuffix ( const boost::filesystem::path &  name, const std::vector< boost::filesystem::path > &  suffixes, const std::vector< boost::filesystem::path > &  compression_suffixes  )

inlinestatic

Perform suffix matching for the given filename.

Parameters

name	the name to check.
suffixes	the suffixes to match.
compression_suffixes	the compression suffixes to match.

Returns

true if the suffix is suppored, false otherwise.

References checkSuffix().

virtual void ome::files::FormatHandler::close ( bool  fileOnly = false )

pure virtual

Close the currently open file.

An exception may be thrown when closing the file, for example if there are problems flushing any pending writes, or if there are any inconsistencies in the metadata which prevent completing any final writes. The causes are reader- or writer-dependent, and the exception type is dependent upon the implementation details of the reader or writer in use. It is advised to always explicitly close writers, since if this is automatically called at destruction time, any errors will be lost. If an exception is thrown, the object may be left in an inconsistent state and should not be reused.

Parameters

fileOnly

close the open file only if true, or else free all internal state if false; only meaningful for readers, since writers will always free all internal state.

Exceptions

On	error; exception type may vary.

Here is the caller graph for this function:

virtual bool ome::files::FormatHandler::isThisType ( const boost::filesystem::path &  name, bool  open = true  ) const

pure virtual

Check if the given file is a valid instance of this file format.

Parameters

name	the file to open for checking.
open	If true, and the file extension is insufficient to determine the file type, the file may be opened for further analysis, or other relatively expensive file system operations (such as file existence tests and directory listings) may be performed. If false, file system access is not allowed.

Returns

true if the file is valid, false otherwise.

Todo:

Could this method be static?
